Title: Complex dielectric
Inventor: TSUZAKI MICHIMASA
IPC: H01G4/12
Filed: 1990-03-22
Abstract: PURPOSE:To make a mixed high specific dielectric constant inorganic substance effectively exhibit a dielectric increasing action for obtaining a complex dielectric having sufficient dielectric constant by dispersing porous inorganic dielectric grains and conductive grains in resin. CONSTITUTION:The complex dielectric has the constitution, in which porous inorganic dielectric grains and conductive grains are dispersed in resin. The porous inorganic dielectric grains are such grains having a large number of pores and crevices opening to the surface while being in a state where resin gets into the gaps. Now, as the porous inorganic dielectric grains, those having an average grain diameter 5 to 100mum and an average specific surface area 0.3 to 7.0m<2>/gr are desirable. Further, the porous inorganic dielectric grains have a case of secondary grains where primary grains have the gaps therebetween and are collected to become porous. Thereby, remarkable dielectric improving effect can be exhibited.

Title: Synchronization system for multi-carrier receiver, synchronizing circuit for multi-carrier receiver, and multi-carrier receiver
Inventor: SHIBATA TSUGUYUKI
IPC: H04J11/00
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To accurately decide a position of an FFT window for fast Fourier transform in a multi-carrier receiver adopting a phase modulation system having a provision for insertion of a guard interval(GI). SOLUTION: A window circuit 220 extracts a component corresponding to one effective symbol length Ts from outputs I, Q of an orthogonal demodulation circuit 210, a serial parallel conversion circuit (S/P) 230 applies serial parallel conversion to the extracted component, a fast Fourier transform device (FFT) 240 applies fast Fourier transform to an output of the S/P 230, and a parallel serial converter (P/S) 250 provides an output of one signal stream. A carrier level measurement circuit 110 measures the power level of each carrier that is an output of the FFT 240, and a flatness measurement circuit 120 obtains a variance of the power levels to discriminate whether or not the window circuit 220 correctly extracts one effective symbol.  Since a window timing is completely synchronized when an output from the flatness measurement circuit 120 takes a minimum value, a PLL 130 applies feedback control to the window circuit 220.

Title: Developing device
Inventor: ASAI ATSUSHI
IPC: G03G15/08
Filed: 1985-04-11
Abstract: PURPOSE:To control securely the amount of a developer into a specific range and to obtain stable images having neither fogging nor variation in density by supplying only a specific amount of developer to a developing part when no developer is detected continuously for a specific detection time. CONSTITUTION:When the total of the time when a sensor 8 detects no developer attains to a specific value, a supply roller 7 is rotated for a specific time to supply a developer. The developer is detected and supplied invariably during the rotation of a developing sleeve 4 and if the developing sleeve 4 stops while no developer is detected, a no-developer detection time is stored and then added to the last detection time after the developing sleeve 4 rotates again. Consequently, the fogging of an image and a decrease in density owing to the excessive supply of a developer are eliminated. Further, the developer is detected during the rotation of the developing sleeve at any time, so that developer is detected in an invariably uniform state and the accurate amount of developer is detected.

Title: Combustor
Inventor: NOGUCHI YUKINOBU
IPC: F24H1/00
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To enable an accurate filling of hot water by controlling a filled hot water amount to the reference water level or a predetermined water level in response to a leaked water amount at the time of water leakage from a bypasses valve in a combustor including a bypass pipe which bypasses a water supply from a heat exchanger and the bypass valve which opens and closes the bypass pipe. SOLUTION: A hot water supply circuit 10 which includes a bypass pipe 13 and a bypass valve 14 for opening or closing the bypass pipe 13 and a reheating circuit 20 are connected with each other by way of a hot water filling circuit 30 thus constituting a combustor 1.

Title: Pressure switch controlling type pump
Inventor: SHIMIZU HIROYUKI
IPC: F04B49/02
Filed: 1981-05-20
Abstract: PURPOSE:To improve reliability of fluid supplying operation, by avoiding frequent repetition of starting and stopping of a pump through employment of such an arrangement that fluid pressure is not applied to a pressure switch when the flow rate of fluid has exceeded a prescribed value but fluid pressure is detected by the pressure switch when the flow rate of fluid has become lower than a prescribed value. CONSTITUTION:When pressure of fluid in a fluid passage is lowered to a prescribed lower limit value of a pressure switch 13, the switch 13 is turned ON and a motor 12 is set into operation, so that fluid is discharged from a pump 11 via a connecting pipe 24. As the fluid passes through an orifice 20, the differential pressure on the opposite sides of the orifice 20 is transmitted to a low-pressure chamber 28 via a pressure transmitting passage 40, thus imparting the pressure difference between the low-pressure chamber 28 and a high-pressure chamber 27. This pressure difference is acted to a resilient member 29 and closes a pressure controlled valve 23. Therefore, when the valve 23 is closed, the pressure switch 13 is kept at the pressure acted just before closing of the valve 23, so that fluid can be supplied in a stable manner without influence of fluid pressure developed when the pump 11 is operated.
